Application filed. March 6, 1911; Serial No. 612,606.

To all whom it may concern:

Be it known that I, JOHN F. PATTERSON, a citizen of the United States,residing at Warren, in the county of Trumbull and State of Ohio, haveinvented a new and useful Sprayer, of which the following is aspecification.

This invention relates to liquid distribution, and more especially tothat class of devices therein known as sprayers; and the purpose of'thesame is to provide a machine for spraying insecticide upon rows ofplants by the atomizer principle. This object is accomplished by theconstruction of sprayer hereinafter more fully described and claimed,and as shown in the drawings wherein Figure 1 is a front elevation ofthis machine complete, and Fig. 2 is a vertical section thereof. Fig. 3is a cross section on the line 33 of Fig. 2 on an enlarged scale andFig. 4 is an enlarged longitudinal section on the line 4ll of Fig. 3.

In the drawings the numeral 5 designates a'font or reservoir havingthrough one wall near its top an inlet or filling opening 6 closed by acap 7 and also having at a low point an outlet opening 8. These openingsmay be formed in a plate 9 detachably secured at 10 to the body of thefont which latter may have the contour best seen in Fig. 1 or any othershape adapted to the wants of the user.

The numeral 11 designates a handle mounted on a shaft 12 whose lower endis detachably connected by thumb nuts 13 with bolts 14 whose heads areseated in the font in such Way as to avoid leakage of the liquidtherein. The numeral 15 designates the cylinder of an air pumppreferably secured rigidly at its upper end to the bottom of said font,16 is a stirrup of a size to receive the foot of an operator, 17 is therod rising from this stirrup and extending throughout the length of thecylinder 15, and 18 is the air valve at the upper end of this rod. Bythis construction it will be seen that when the operator places his footwithin the stirrup 16 and draws upward on the handle 11 he causes thecylinder to ascend on the valve so as to take in air, and when he pushesthe handle downward he causes the cylinder to descend on the valve so asto trap the air already taken in; and the manner in which I use this airfor spraying on the atomizer principle will now be described.

The numeral 20 designates a collar fixed to the wall of the font aroundits outlet opening 8, and 21 is the tubular body of a sprayer nozzlewhose open inner end surrounds this collar with packing 22 between themto make a liquid tight joint. Through the wall of the font 5 extends abolt 23 which passes axially through said collar and throughout thelength of the nozzle 21, and in the closed outer end of the latter is acentral hole through which this bolt passes so that its tip may receivea wing nut 24. By this construction the nozzle 21 is mounted revolublyupon the collar 20, and the outlet opening 8 communicates with theinterior of the nozzle. The latter has disposed within it a series ofjet tubes 25 extending at right angles to its axis and with their outerends 26 projected through its wall as best seen in Fig. 3, the innerends of course communicating with the interior of the nozzle. Securedalong and upon the wall of this nozzle and extending at right angles tothe length of said tubes is an air tube 27 whose wall is pierced with aseries of fine perforations 28 disposed opposite the outer ends of saidjet tubes 25 and in such direction that said perforations will directthe air across the axis of the jet tubes and atomize the .liquid thatmay be contained within the latter. The outer end of the air tube 27 isclosed as at 29, and upon its inner end is slipped a rubber hose 30which is bent around and communicates with the interior of the aircylinder 15 of the pump, as by means of a nipple 31 projecting from thelatter as seen in Fig. 2.

I have described but one of the nozzles 21 and its connection with theinterior of the air pump, but it will be seen from Fig. 1 that Ipreferably employ two such nozzles and of like construction, and ofcourse I provide two outlet openings 8 through which to feed the nozzleswith liquid. By turning these nozzles on their axes they may be causedto deliver liquid at different and more or less divergent angles, sothat the operator can walk between a row of plants and sprinkle bothrows with whatever liquid his font contains.

It is obvious that the device can be used as a sprinkler by puttingwater into the font, or as an insecticide distributer by putting liquidpoison into the tank.

Hitherto much difliculty has been experienced with insecticidedistributers because of the fact that when their fonts or tanks werenearly full the delivery was too copious and the plants were injured bythe poison, but on the other hand when their tanks were nearly empty thedelivery was too restricted and the plants did not receive enough of thepoison. By my improved construction above described, the liquid withinthe body of the font 5 flows out the opening 8 into each nozzle 21 untilit traps the air within the latter and no more liquid can pass out, andthis trapping is permitted by the oblique disposition of the jet tubes25 as seen in Fig. 3. WVhen the pump is actuated, its air forced througheach of the tubes or sections of hose 80 is directed in fine streamsthrough the perforations 28 across the outer ends 26 of said jet tubes25 and atomizes the liquid in the latter and directs it in the shape ofspray onto the plants being treated the angles at which the jets ofsprayare directed being regulated by the axial setting of the nozzles 21 ashas been explained. When the operator draws upward on the handle 11 theair admitted through the fine perforations 28 is not suflicient to fillthe cylinder 15, and hence fresh air passes upward past its valve 18ready for a renewed operation. Meanwhile more liquid flows from the font5 through the openings 8 into the nozzles 21 to replace what has beenblown out of the latter, in a manner which will be clear.

It will be obvious that the general construction of this device is suchthat it can be carried by hand with ease, even when filled to its limit,and the operator isnot required to carry anything at arms length becausethere is nothing on the rear side of the device (the left in Fig. 2)which would injure his clothing or his person if he held the machineclose against his body. From time to time the cap 7 can be removed andthe font refilled. The removability of the handle 8 through its thumbnuts 13 renders it possible to substitute a shaft 12 of differentlength, in case the operator is taller or shorter than'a man of averageheight.

The material and exact construction of parts are not essential to thegist of this invention.

What is claimed is:

1. In a sprayer, the combination with an upright font having an outletopening in its side wall near its bottom, a handle rising from saidfont, a pump barrel depending from said font, a rod sliding therein, avalve at the upper end of the rod, and a stirrup at its lower end; of acollar projecting from said font and inclosing said outlet opening,

a nozzle axially adjustable around said collar and having a jet tube, anair tube extending across said jet tubeand having a perforation directedacross the outer end thereof, and a' flexible connection between theinterior of the pump barrel and the said air tube.

2. In a sprayer, the combination with an upright font having an outletopening inits side wall near its bottom, and an air pump; of a collarsurrounding said opening, a nozzle axially adjustable upon said collarand having a jet tube whose axis lies in a plane at right angles to theaxis of said nozzle, an air tube having a perforation directed acrossthe outer end of said jet tube, and a flexible connection between saidpump and air tube.

3. In a sprayer, the combination with an upright font having an outletopening in its side wall near its bottom, and an air pump;

of a bolt projecting thrtiugh the wall of said collars fixed around saidopenings, nozzles rotatably mounted upon saidcollars, a series of jettubes within each nozzle whose axes lie in a plane at right angles tothe axis of said nozzle, and whose outer ends extend through the wall ofthe nozzle, air tubes secured along the outer walls of the nozzles inproximity to said jets and having fine per forations directed across theouter ends of the jet tubes, and means for directing a blast of air intosaid air tubes.

In testimony that I claim the foregoing as my own, I have hereto afiixedmy signature 7 Copies of this patent may be obtained for five centseach, by addressing the Commissioner of Patents',
